To determine how much larger a 10" low-pressure distribution (LDP) system is compared to a conventional system, it is essential to understand the relationship between these systems and their respective dimensions.

A 10" LDP is typically larger in diameter than conventional systems, which often have smaller diameters. When comparing sizes, percentage increases are calculated based on the difference in size relative to the original size. In this case, if we assume that a conventional system is a standard size, the increase to a 10" diameter represents a notable shift.

The 120% increase indicates that the size of the 10" LDP system is 120% of the original size of the conventional system. This suggests that the LDP is not only larger than the standard system but also significantly more effective in managing waste due to its design, which may distribute effluent more evenly and efficiently.

Understanding this percentage helps in grasping the impact that size and design differences have on the functionality of septic systems. The 120% increase highlights how a larger diameter can improve capacity and performance, making it an important measurement in the context of septic system installations.
